How To Use

This is a one-stop shop of readily available geospatial information for use in severe weather responses.

Each of the information categories has each dataset previewed, with a brief explanation and links, that you can use to add to your maps.

Historical Flood Extent

This shows flood-return data from Land Resource Information System (LRIS).

Symbology is for 1 (Slight /1 in 60 years) to 6 (Very Severe/ 1 in 5 year) flooding return in an area.

Sentinel-2 Imagery

This shows real-colour imagery from the Sentinel-2 Satellite, synced and processed and disseminated by Esri. (note: up to 10m resolution)

Technical Tips

What is listed below has evolved from previous responses, consider them a guide - not a rule!

Layers

  • When creating your maps, remember layer order is important! Stack your point layers on top, then lines, with polygons beneath (unless these are alert areas - stack these on top)
  • Rename the layer in your web map layer list (shorter names, consider a prefix "Base Data - XXXXX")
  • Apply transparency for any polygon and raster Layers
  • Change the symbols, and ask for feedback from those using it on what they need
  • Use filters where for your datasets
  • Change popups from the default

Maps

  • Change the basemap, and ask for feedback from those using it on what they need
  • Consider a 3D scene for some displays
  • Less is more, consider another map if it becoming too busy

Apps

  • If the user is just viewing data - consider a dashboard
  • Less is more, consider another app if there are too many widgets
  • When you scale up, lots of apps are going to be built. Considering embedding them all within a storymap, hub site or an experience builder app to provide a single URL to remember for all geospatial information!
